AGITATOB; OB SHAKER FOB STOVES 0B FURNACES.

' Application filed May 7, 1923. Serial No. 637,318.

To alt whom it may concern:

Belt known that I, NICHOLAS J. ZUZULTN, a citizen of the United States, residing at Minot, in the county of Ward and State of.

North Dakota, have invented certain new and useful Improvements in Agitators or Shakers for Stoves or Furnaces, of which the following is a specification.

My invention relates to agitators or shakers for stoves, furnaces, or the like.

An important object of the invention is the provision of a device of this character, which will be capable of use with soft coal or lignite burners in such a manner that the clinkers and coal are all consumed.

Another object of the invention is to provide a device of this character. which will be in the nature of an attachment and which may be readily attached to any furnace now in use.

A further obiectof the invention is to provide a device of the above mentioned character, which will be characterized by extreme simplicity. and is strong and durable. v

ther objects and advantages of the invention will be apparent during the course of the following description. a

In the accompanying drawings forming! a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a perspective view of a furnace provided with my invention,

Figure 2 is a side elevation of parts being in section,

Figure 8 is a transverse section taken through the shaker, showing; the different portions of the shaker arms in dotted lines,

Figure l is a central longitudinal section through the device, and, V

Figure 5 is a perspective view of a modified form of the device.

In the drawings, wherein'for the purpose of illustration is shown a preferred embodiment of my invention. the numeral 10 designates a furnace having a grate 11 of the usual construction. The furnace casing is provided with a threaded opening 12 inits front portion, said opening being arranged a substantial distance above the grate 11 and adapted to receive the exteriorly threaded end of a tubular sleeve 13 having a radial flange 13 at its opposite end. Suitable clamping rings 14 are screwed onto the sleeve 13 and arearranged one on either side of the furnace casting. These clamping; rings are provided the same,

with extensions 15 and a bolt16 serves to clamp the clamping rings to the wall of the furnace. This construction affords a very rigid mounting for thesleeve 18.

A shaft 17 fits loosely within the sleeve, and has a squared end18 for the reception of a shaker crank 19, whereby the shaft may be rotated within the sleeve. This extends inwardly to about the center of the furnace and the shaft extends therebeyond, and is provided with an enlarged head 20 which is eccentrically mounted on the shaft and which has its end screw threaded.

Radially extending arms 21 extend one to each side of the head 20. Each of these arms comprises a substantially flat body portion 22 which has an opening near. its ends which receives the eccentrically mounted head 20. This body portion has both edges curved so as to converge outwardly, and merge into an upstanding prone 23. Similar prongs 2 1 are carried by the body portion and are arranged to either side of the central prong so as to form a fork shaped agitating element. A nut 25 is screwed onto the head 20 and serves to reta n the armsthereon.

A supporting, plate 26 is carried by the sleeve 13 and is arranged beneath the head 20 and arms 21. This plate is adapted to support the arms in a substantially horizontal position as without th s support these arms would swing downwards into a vertical position.

In operation. when the shaft 1.? is turned by the crank 1.9. the arms 21 will partake of a combined rocking and recipro ating motion. This is due to the turning of the eccentrically mounted head 20 which as it revolves will act as a crank and reciprocate the arms. The inner ends of these arms will also have a vertical movement due to the crank like movement of the head 20 and this vertical movement will be translated into a rocking motion due to the curved lower edge contacting with the supporting plate. This is shown in Figure 3 by the dotted lines. The arms are prevented from sliding off of the head by the flange 13 on one side and by the nut 25 on the other'side.

In the modification shown in Figure 5 the supportingplate is dispensed with and the sleeve 13 is provided with a radial extension 27 having; its end bifurcated, forming a slot 28. The arm 29, nearest the sleeve carries a lateral extension 30 near its outer end which has a rounded shank with an enlarged head at its end. This shank is adapted to slide in the. slot 2 8. A lateral lug or pin 31 is carried by the opposite end of the arm 29 and is" arrangedion the side farthest from the sleeve 13. This pin 81 enters an opening in the arm32 and'serves to support the same. When the shaft is rotated the arm s vvill partake df the same combined reciprocating and rocking motion as in the other form ofthe'inve'ntionL The extension 30 will'reciprocate'in the slot/28 and Will also serve as a pivot Whe inthe inner end of the arm moves v'ertieally thereby resulting in a rocking motion, Due to the 31 the other arm ,tv ill partake of the same movement. The crank 19 need not be rotatedbutneed only be oscillateda's'is usual in a grate, v I I 'The agitation caused byg hererred agitat ing members will cassette fiileashes to descend' and cause the {fire toj come" down to and around the; mechanism (Se as tohold the. unburned clinkersin suspnsioii' nd thereby cause" a more cdinplete cdn'ibustidn which will esurgent; m'oi'e e'condmicfal use of soft coal'and lignite.

It is to be understoodfthat theform of my invention herewith shov'vn'and described is to be taken asapreferred example of the same, and that variduschange'sin the shape,

form, size and arrangement of parts may be resorted to without departingfrom the spirit of my inveiitiono'r the scope" or the siibjoined claims! J r a Having thus described rfiy invention, t lea n; r
